Looking at the images, how many chromosomes are there in a
typical human? -
correct answer ✅46
What do you notice about the chromosomes in both images? -
correct answer ✅They come in pairs
Why are chromosomes a poor way to think of how DNA is normally
stored? -
correct answer ✅DNA only looks like this during replication
The top image, called a karyogram or karyotype, is from a human
female, while the bottom one is from a human male. What major
difference do you notice? -
correct answer ✅The male has a set of mismatched chromosomes
Thinking back to what you learned about genetics, what do the
colored bands on the chromosome represent? -
